 Overview:
  Nagios is prone to an unspecified privilege-escalation scripting
  vulnerability.

  An attacker with low-level privileges may exploit this issue to
  bypass authorization and cause arbitrary commands to run within the
  context of the Nagios server. This may aid in further attacks.

  Few technical details are available at this time; we will update
  this BID as more information emerges.

  The issue affects versions prior to Nagios 3.0.5. 

 Solution:
  The vendor has released updates. Please see http://www.nagios.org/
  for more information.
